			<h1>Spell-checking</h1>
			<p>The <a target="_blank" href="https://www.onlyoffice.com/en/presentation-editor.aspx" onclick="onhyperlinkclick(this)"><b>Presentation Editor</b></a> allows you to check the spelling of your text in a certain language and correct mistakes while editing. In the <em>desktop version</em>, it's also possible to add words into a custom dictionary which is common for all three editors.</p>
			<p class="note">Starting from <b>version 6.3</b>, the ONLYOFFICE editors support the <b>SharedWorker</b> interface for smoother operation without significant memory consumption. If your browser does not support SharedWorker then just <b>Worker</b> will be active. For more information about SharedWorker please refer to <a href="https://javascript.plainenglish.io/introduction-to-shared-workers-533d9abe9de3">this article</a>.</p>
			<p>First of all, <b>choose a language</b> for your presentation. Click the <span class="icon icon-document_language"></span> icon on the right side of the status bar. In the opened window, select the necessary language and click <b>OK</b>. The selected language will be applied to the whole presentation. </p>

			<p>To <b>choose a different language</b> for any piece of text within the presentation, select the necessary text passage with the mouse and use the <img alt="Spell-checking - Text Language selector" src="../images/spellchecking_language.png" /> menu on the status bar.</p>
			<p>To <b>enable</b> the spell checking option, you can:</p>
			<ul>
				<li>click the <div class = "icon icon-spellcheckdeactivated"></div> <b>Spell checking</b> icon at the status bar, or</li>
				<li>open the <b>File</b> tab of the top toolbar, select the <b>Advanced Settings</b> option, check the <b>Turn on spell checking option</b> box and click the <b>Apply</b> button.</li>
			</ul>
			<p>Incorrectly spelled words will be underlined with a red line.</p>
			<p>Right click on the necessary word to activate the menu and:</p>
			<ul>
				<li>choose one of the suggested similar words spelled correctly to replace the misspelled word with the suggested one. If too many variants are found, the <b>More variants...</b> option appears in the menu;</li>
				<li>use the <b>Ignore</b> option to skip just that word and remove underlining or <b>Ignore All</b> to skip all the identical words repeated in the text;</li>
				<li>if the current word is missed in the dictionary, you can add it to the custom dictionary. This word will not be treated as a mistake next time. This option is available in the <em>desktop version</em>.</li>
				<li>select a different language for this word.</li>
			</ul>
